TELEADJUSTER FOR Application filed November To all v /20m it mayconcern:

Be it known that I, PAUL KAMINsKI, a citizen of the German Empire,residing at lierlin-Pankow, Germany, have invented certain new anduseful Improvements in a Teleadjuster for Guns and the like, of whichthe following is a specification.

Heretofore, arrangements have become known, which allow a control ofguns or the like, as to their elevation as well as to their lateraldirection, from one direction telescope, without the adjustment in thehorizontal plane being of any influence on the elevation.

The present invention has for its object to provide'a particularlyappropriate con-,

struction of such an arrangement, which allows the use of the sameelectric transmitters tor the search-lights, range meters and telescopescontrolled by the direction tele scope and which are adjusted parallelto the latter, as for the control of the guns, which besides mustreceive the angle of elevation.

For this purpose, according to the present invention, the non-stationarytransmitters of the arrangement, which move with the direction telescopeand which transmit the parallel position to the direction telescope, aremade to adjust separate stationary electric auxiliary receivers. V

The adjustment of the following pointers, following the position of thepointers of the auxiliary receivers is then added, in a way known in theart, to the movement of the range adjuster-of the stationarytransmitters controlling the guns.

The accompanying drawing shows, diagrammatically, aperspective View ofthe improved arrangement.

The direction telescope F is, in a way known in the art, adjustable in aperpendicular plane on its pivot a by means of a crank 76, worm c andtoothed sector d, while the bracket h carrying the pivot a of thedirection telescope F can be slewed together with the latter, in ahorizontal plane -by means of a crank b, said latter adjustment beingtransmitted, in a way known in the art, over a gearing 3 to the electrictransmitters S for the horizontal direction, and the required correctionfor the concentration correction being added to said transmitters fromthe drum T, over the inter- GUNS AND THE LIKE.

In the gearingabovementioned, the automatic transmission to the planet wheel '7), iseffected: for the value A through the transmission gearing A, of thesine for the lateral adjustment through the sine line K, and for thevalue of the range through the adjustment of the drum T The tele-controlof the elevation of the guns, according to the invention, takes place asfollows 2-- The crank 70 turns over intermediary gearings 2', Z, 29,,30, electric transmitters (/2 for coarse and fine adjustment, which aremounted on the revoluble bracket h. The training of the directiontelescope F in a horizontal plane becomes thereby independent from themovement in a perpendicular plane, so that the usual mechanical bevelgearings. which hitherto were to ensure said independence, are omitted.Said non-stationary transmitters g g, which thus participate in thehorizontal training of the direction telescope, act, in one of the knownways: for instance the known alternating current systems, eitherdirectly on the receivers of search-lights or the like, which (lo-notrequire a ballistic elevation angle, or on stationary auxiliaryreceivers 00,, w, for the guns, which must receive the ballisticelevation angles as an addition.

On said receivers .75, m following pointers e 2, are adjusted in a wayknown in the art, and said adjustment is transmitted to the transmitters9,, g, for the guns over the gearing m, u, q, o, p, and planet wheel 72,To said transmitters, the ballistic elevation angle is added from theadjustable drum T through the planet wheel 79,, and and the gearing 7),,t, 0.

If the direction telescope F is situated above the guns, for instance inthe top of a man-of-war. said elevation must be considered for firing.The value of said elevation, the so-called angle of dip, is

=%: E designating the range and H as known, the value sin at Edesignatthe perpendicular distance between gun and can be directlytransmitted to the transmiters g 9 for which purpose the range value ofthe drum T is made to act as an addition on the planet wheel p throughan intermediary gearing 1' 1' 1' e, 102, w 2, while the constant value His arranged in the transmission ratio, for instance of the wheels 'w 10It is immaterial for the scope of the invention Whether the adjustmentof the drums T and T takes place by hand or by a clockwork or the like,and Whether the transmission at the auxiliary receivers w, and a2, takesplace on the follow-thepointer principle or by any hunting principle.

What I claim, is

1. In an arrangement for the telecontrol of guns or the like, adirection telescope and stationary transmitters for transmitting thetraining movements of the telescope with respect to the concentrationcorrection, and non-stationary transmitters for transmitting thevertical movements of said telescope to the guns, said directiontelescope being located higher than the guns, a drum calibrated for therange, and suitably connected and operated to impart the concentrationcorrection to the stationary transmitters for the bearing angle, andspecial v and gearing for connecting said drum also to saidnon-stationary transmitters for the vertical movements of saidtelescope, said special gearing having a suitable ratio for guns, a drumcalibrated for the range suitably connected and operated to impart theconcentration correction to the stationary transmitters for the bearingangle and special gearing for connecting said drum also to saidnon-stationary transmitters for the vertical movements of saidtelescope, said special gearing having a suitable ratio for correctingthe angle of di P and stationary auxillary receivers adapted to be actedupon by said non-stationary transmitters, and being mechanicallyconnected to said stationary transmitters which control the setting ofthe guns and means for adding the angle of elevation to the adjustmentof said stationary transmitters.
